Oxiation Of HEH And Reaction Of NO With Allenes

This thesis contains two parts. The first one outlines the recent progresses in the application of co-enzyme NADH model compounds and methods of aromatization of Hantzsch 1,4-Dihydropyridines (HEHs). HEHs were efficiently oxidized to Hantzsch pyridines in dichloromethane with a catalytic amount of radical cation tris(4-bromophenyl)aminium (TBPA~+(?)).In the second part, a review on NO's chemical features is given. Otherwise, the progresses on the reaction of allenes are briefly introducted. The preliminary research on the reacton of NO with allenes at room temperature was reported.
